I am currently most of the way through a 1x10 conversion of an old (early 90s) mountain bike. As part of the process, I had to replace the rear hub, and the only one I could find locally came installed on a rim (Equation aluminum, labelled 559x16, measured 16.25mm interior width). The old rims were larger (Araya, labelled 26x1.50, measured 20.25mm interior width). I own two nearly-new (well, 15 years old, but never really ridden) Maxxis tires, labelled 56-559 as well as 26x2.10.
I understand that tire and wheel sizing is a deep, dark hole, but from Sheldon's chart, it looks like these tires are probably too wide even for the wider of my rims, and definitely too wide for the new, narrower rim.
So I'm wondering what my best strategy is:
- Just run with the tires and mismatched rims I have, the difference is too little to matter
- Run with mismatched rims but replace the tires with either a matched set or two individual tires that match their respective rim
- Move the new hub to the old rear wheel and run with the tires I have (noting that I have none of the equipment I'd need to properly build a wheel)
- Replace the front wheel with a rim that matches the rear wheel and run with the tires I have
- Replace the front wheel and both tires because those tires are way too wide for 16mm rims
- Any other novel, clever suggestions you might have
